The machining allowance on the finished sizes is sufficient for lengths up to 250 mm. For finished part lengths over 250 mm - especially diameters over 172 mm - a higher machining allowance is necessary.

Standard lengths: ca. 3000 mm, 2000 mm, 1000 mm and 500 mm.

Our foundries are able to centrifugally cast (flanged) tubes in any size, up to a diameter of Ø 2000 mm and length up to 3000 mm in all current alloys.

The differences between aluminiumbronze according Din 1714 and DIN 17665

Aluminiumbronze according DIN 1714 and EN 1982

These standards are applicable for all aluminiumbronzes which are produced by continuous casting and centrifugally casting. The given machining allowances are in use for maximum part lengths of 250 mm. For longer part lengths more machining allowance is necessary. The tolerances on the cast size are mostly -0/+2 mm for wallthicknesses of 12 mm and more. Deviations are always possible.

Aluminiumbronze according DIN 17665, 17672 en EN 12163, 21267, 12420

These standards are applicable for all aluminiumbronzes which are produced by extrusion or extrusion and cold drawing. This production form mainly produces round bars, hexagons, squares and rectangles. Material produced according these standards does not have a machining allowance. Tubes can only be produced according DIN 1714 (see above).
